The Diplomat Season 3 Debuts on Netflix With Bigger Stakes and a West Wing Reunion

Reviews praise Keri Russell as the series shifts further into the White House, with Season 4 already planned.

Overview

  • All eight episodes of Season 3 are now streaming on Netflix as of October 16, 2025.
  • The new season broadens the show’s focus from embassy corridors to Oval Office power, heightening tensions in U.S.–U.K. relations without abandoning its intimate character drama.
  • Allison Janney takes center stage in the presidency and Bradley Whitford joins as First Gentleman, reuniting the West Wing pair and expanding the ensemble’s dynamics.
  • Critical response highlights Russell’s lead performance and the show’s brisk, procedural energy, with some reviewers noting a more escapist tone and uneven romantic focus.
